Debug hud shaders are only used by debug hud to display shadow map. These 
shaders should not bother you at all. They don't affect your scene, scene is 
drawn by mainVertex/mainFragment/shadowVertex/shadowFragment shaders. See 
osgshadow example with following options: -4 --lispsm --debugHUD and see 
what they do.
